Abstract
One of the most important problems associated with the design of external travelling wave optical modulators operating at very high frequency is the reduction of microwave loss associated with the electrode structure. With this in view, a new design for a Ti:LiNbO/sub 3/ narrow-band optical modulator is proposed for operation at 94 GHz. It uses a low-loss loaded transmission line with dielectric overlay and uses phase-reversals to achieve phase matching. Numerical simulations predict a required 21-dBm drive power for full on-off switching at 94 GHz.
